APE3rBOX Application filed August 4,

To aZZ whom it me concern:

Be it known t at l, EMIL JAonnnnno, a SUbJQCG of the German Emperor, and a resident of 107 Himmelgeisterstrasse, Dusseldorf, Germany, manufacturer, have invented certain new and useful Improvements in Paper--30 Machines, of which the following is a statement.

In the paper box machine, which is, for example, described in the United States specification 1,001,856 paper boxes are made and by means of a second, similar folding device paper sheets are folded around and gummed to the thus made bones, while the latter are still on the cores. With such machines it may, now, occur, that for some reason or other the paper feed to the first folding device fails, so that this foldin device operates idle and no box is forme on the respective core. \Vhen, then, this core reaches the second folding device, which uins the paper sheets around the formed ones, the paper sheet will be wrapped around the empty core, and gummed to it.

The object of the present invention is to obviate this disadvantage.

The present invention consists in an arrangement which will automatically disengage the feed of the paper to the second "folding device, when there is no box on the core, around which the paper sheet would be wrapped.

In the accompanying drawing the present invention has been exemplified, Figure 1 being a side elevation, Fig. 2 a cross section.

The pile of sheets A rests on a plate 3 between the vertical rails 1. These rails 1 are secured to a plate 5, which is guided in a vertical direction by means of guide rods 6 in blocks '7. The plate is vertically reciprocatcd by means of a double-armed lever 8 and a can: disk 11 fitted to shaft 50, The one end of said double-armed lever enga es under a cross piece 9 forming connection etween the bottom ends of the rods 6, and the other end of said lever carries a roller 8, which rides on the cam disk 11. Above the one edge of the pile of sheets A is journaled a shaft 10, carrying the gum applying and taking oil segments and lodges, which shaft is each time intermittently revolved by one revolution by means not shown in the drawing. whereby the known segments 12 and ledges are simultaneously provided with gum by means of a gnmming device consistof the rollers 17, 18, 19.

The plate 3 carrying the pile of sheets is coupled with a toothed rod 20, n the teeth of whichengages a pawl 21, which holds down the rod and the plate 3 contrary to the pull of the springs :22. The springs are secured to the plate 5 and to the lower end of the rod 20. The pawl 21 is pivoted to the one arm of a double-armed lever 23, the other arm of which carries a roller 9' which rideson a cam disk 24 fitted to the shaft In the pawl 21 is furthermore fitted a pin 25, which on the rockin of lever 23 strikes against an inclined surtace 26, which is provided on one of the guides 7 Beneath the shaft 10 is journuled a roller 27 in arms 27,'Which-are rigidly fitted to a shaft 48. The shaft 48 itself is journaled in the-body of the machine. The roller 27 is driven by means of a spur gearing 29, 30 from the shaft'lO.

The lever 23 which carries the pawl 21 is in a bracket 13 and has in its upper end a pin g, which projects through the platen It for the bottom llaps of the box formed on the core 2', and can emerge a little on the inside of this platen h. The cores 1' are movably arranged in known manner (United States specification 1,001,856). so that one after the other will arrive infront of. the platen h. The cores are provided with holes y in their face ends, into which the pin q can enter, when the respective core arrives empty in front of the platen ii. The bolt 15 carrying the platen is litted adjustable by means of screws 16 in an arm is, which is pivotally fitted on a pin Z in the bracket 28 and is linked to lever it by means of rod This lever 11 is keyed together with lever .o to shaft 7) iournaled in the body of the machine. The lever 0 is linked to a rod 52 which carries at its lower end a fork and a roller 54. The fork encircles the shaft 50 onwhich is fitted a cam disk, against which the roller rides. On. the shaft 44 of lever 23 is also rigidly fitted a second lever g, which is hingedly connected by rigidly "'**d to shaft 48 can engage, the said ieve sting coupled to a lever 49. v The lever as; h at its end a pin 56, which is grasped hooked end of rod 47, linked to the hand-lever t1. lhis handlever is ivotally journal-led on. the body of the mac inc and is coupled by a red re with a cam lever y journaled on the bracket 51. One of the levers 27 carries a roller '0, which lies in the track of a cam w fitted to shaft 10. Between the gum applying segments 12 engage the stationary strippers 31, the front edges of which are situated close behind the roller 27, and which extend up to close in front of two rollers 32 and 33. These rollers are continuously revolved in opposite directions. Behind the rollers felt plates 34 are provided, over which the cores 7; pass.

After each revolution the shaft 10 stops in'such a position, that the segments and ledges are directed verticall downward. While the shaft 10 is at'rest, t e rods 6 with the plate 5 are lifted by lever 8 and the cam disk 11, while, however, the pawl 21 holds down the plate 3 with the pile of sheets. Then the recess 24* in the cam disk passes beneath the roller 23 on the double-armed lever 23, so that the pawl can rise. In consequence thereof the springs 22 can move the rods 20 with plate 3 and pile A upward. The pin 25 on the pawl 21 which is likewise raised, strikes against the surface 26, whereby the pawl is disengaged from the teeth "of the rod 20. The rod 20 is therefore perfectly free and the springs 22 can press the pile of sheets, irrespectively of the number of the latter, and its height against the segments 12 carrying the gum and the ledges on shaft 10. Immediately after the lever 8 lowers the rods 6 with the plate 5 a short distande, and thereupon the rocking oflever 23, the awl of which 21 reengages with the test in the rod- 20 mores thq iplate 3 downward with the pile of sheets. e uppermost sheet erthe pile A, howevenadheres to the .gumrned segments 12. Simultaneously with the downward movement of the pile the shaft 10 is revolved by exactly one revolution by means of the gear not shown in the drawing. The sheet adhering to the segments 12 is carried along thereby and pressed by the like- Wise revolving roller 27 tightly against the gunirned segments and ledges on shaft 10,

so that it is g 'nnned correspondingly with the surfaces of these parts. The strippers 31 then detach the sheet from the gunnning roller and take it between the rollers 32 and v 33 which convey it to the foldin' platens.

Before the roller 10 has complete itsr'evo lution, the segments and ledges on it are again afresh by roller 19'. If, now,

there is no box on the core a arri ing in front oi the presser platen it, the pin g,

*;which is advanced by the spring a acting pulled 05 from it by the segments 12.

Therefore no sheet will be gummed and wrapped around the empty core, so that the latter will not be soiled. By holding down the pawl 21 however, also the plate 5 and the lug t will be held in raised position, so'that so the pressure roller 27, which has been pressed down by. the cam w shortly before the preceding revolution was completed, will likewise remain in" its raised position by the lever u remaining engaged with the g5 lug r so that the gununing roller, which 7 now runs idle, will not be soiled. When,

however, there is a folded box on the core i arriving in front of the platen it, the hofe torn flaps will prevent the pin 9 enterin into the hole 7', and the hook b is retains The pawl 21 can, therefore, rise so that the lug t is drawn from the'lever a, and the roller 2? is pressed by the spring 57 acting on the lever 21. against the roller or against the sheet of papal on the same respectively.

For stopping the machine the handlever i1 is thrown up, whereh' thecam lever y bears against lever 23 an thereby prevents ce the pawl 21 from rising. At the same time the rod 47 gulls with its hooked end s pressure re or .27 from the roller.

I claim:
